10~2400 Pair Telephone Cable 0.4~0.5mm Underground Armoured/Unarmoured.


This specification covers multipair cables used in the provision of voice and data services and the interconnection of electrical equipment and instruments, particularly in and around process plants, where transducer generated signals are transmitted through marshalled circuits to panels, controllers and associated devices.

– Application: Cable is mainly used to transmit audio, 150k Hz and below, the analog signals and 2048kbit / s and below, the digital signal. Under certain conditions, can also be used to transmit 2048 kbit / s or more digital signals.

– Installation: Duct / Aerial (non-self-supporting aerial)/Buried.

Product Characteristic:

– Moisture barrier and polyethylene jacket enhances anti-jamming and moisture proof performance.

– Fill oil enhanced cable moisture proof performance.

– Temperature range during operation (fixed state): -20°C ~ +70°C.
